A ship name for the romantic pairing of VTubers Ouro Kronii and Nanashi Mumei. The "kron" comes from Ouro (Kron)ii and "mei" from Nanashi Mu(mei). Both belong to the VTuber group "Hololive" and are part of the 2nd English generation named "Council". In lore terms, Ouro Kronii represents the warden of time while Nanashi Mumei is seen as the guardian of civilization. These lore roles are often displayed in their ship pairing. Additionally, it is a popular headcanon for Ouro Kronii to be drawn as a crow (due to her seemingly dark nature and her name being pronounced "crow"nii). In combination with this, Nanashi Mumei's character is based on a barn owl meaning it is not uncommon to see the ship being expressed as a pair of birds on top of their human form.
